The Fred Hartman Bridge is a cable-stayed bridge in the U.S. state of Texas spanning the Houston Ship Channel. The bridge carries 2.6 miles (4.2 km) of State Highway 146 (SH 146), between the cities of Baytown and La Porte. The bridge is also expected to carry State Highway 99 (SH 99) when it is completed around Houston.

A cable-stayed bridge has one or more towers, from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.
The Russky Bridge in Vladivostok has a central span of 1104 metres. It is the world's longest cable-stayed bridge.

Chain-stayed bridge by the Renaissance polymath Fausto Veranzio, from 1595/1616. Prior to industrial manufacture of heavy wire rope (steel cable), suspended or stayed bridges were firstly constructed with linked rods (chain).
